OPTION - 1Firstly, the starter ends with 'opinion'. Hence, it cannot continue with the same word. So, option 3 is eliminated. Also, an article is followed by EITHER a noun or an adjective. Hence, sequence QR in option 4 is incorrect. Since, starter ends with a noun and Q starts with an adjective. But, this is grammatically incorrect because adjective COMES before noun. Hence, option 2 is incorrect. Hence, option 1 i.e. RQP is the correct answer.
